Construction of the Bingham and Garfield Railroad commenced in 1907 to transport ores from Bingham to the Magna and Arthur mills at the northern base of the Oquirrh Mountains. Utah Copper's Magna mill, a 6,000-tpd operation, started in 1907, while Boston Consolidated's 3,000-tpd Arthur mill opened in 1909.
